The i2cStick is our personal,powerful, and pocket-size
I2C Bus host adapter. Just load our free software, plug the
i2cStick
into a USB port, and you will be sending and receiving I2C messages
in seconds.

The i2cStick is our personal, powerful, and pocket-size I2C
Bus host adapter.
USB-IF
and Microsoft WHQL Certified, the
i2cStick
will operate with any Windows 7, Vista, or XP PC. Typical applications
include product development and testing, EEPROM programming, device control
and sensor networking.

Over the past few years, the I2C Bus has expanded from simple
control to data intensive applications. As new uses arise, bus bandwidth
and message overhead have become key issues in product design and testing.
The i2cStick, our fifth generation adapter for the I2C Bus,
addresses these issues by supporting several I2C bus speeds,
including fast mode (400kbit/s), and
USB transfer rates up to 12 Mb/s. Implemented using a high-performance
bus co-processor with optimized instruction set, the adapter also includes
large message buffers (256 bytes) to reduce host computer and bus overhead.
In addition to operating as a bus master or slave in a multi-master system,
the i2cStick includes Packet Error Check (PEC) detection.

Thanks to its USB-based Virtual Communications
Port (VCP) driver, the i2cStick will work with RS-232
based applications written for our iPort/AFM or iPort/AI I2C
Bus host adapters, and is compatible with applications for our iPort/USB
adapter.

Start sending I2C messages in minutes using our Message
Manager or Message Center applications included with each adapter.
You can also use your computer's terminal emulation software (like Windows'
Hyperterminal Program), or create your own custom I2C applications
using any programming tool that can access your computer's (virtual) serial
port.
